this looks like a bug in the python bindings to me
--- Begin Message ---
Package: python3-notmuch
Version: 0.18-3
Severity: minor
If a message starts with the "From " postmark (i.e., it's in the mbox
format), and you ask the get_header() method for a non-existent header,
it raises NullPointerError, instead of returning empty string.
Now, I realize that support for indexing mbox files has been dropped,
but users might still have them on disk, indexed by an old version of
notmuch. This is how I discovered this bug.
I've attached my crafted mail archive (which I indexed with wheezy's
notmuch), and the script that I used for testing:
$ python3 test.py
OK
NullPointerError()
